Abstract
A current protection device includes stacking first substrate, support layer, circuit layer, and second substrate. The surface of the first substrate attached to the support layer is an arrangement surface, and the surface of the second substrate attached to the circuit layer is a contact surface. The contact surface has a second recess, and the arrangement surface selectively has a first recess. The recesses serve to release pressure and to ensure the circuit is entirely blown by over current so as to prevent an arc effect. Besides the over current protection for electric equipment, the current protection device can be applied to light and small electronic device.
